TO ALL WHOM- IT .MAY CONCERNz- Be it known that I, PHILIP HILL, of Philadelphia, Pennsylvania, have invented an improved Damping Device; and I dohereby declare the Afollowing to bey a full, clear, and exact description of the same, reference being had to the accompanying drawing', and to the letters of reference marked thereon.

v My invention consists of a cup, a'roller, `andi-a bandvotl cloth or felt'extending over the roller and inton'aterv in the cup, as `fully described hereafter, so that when the exposed portion of the band becomes so dry that a stamp or`other article pressed onfth'e same cannotbe' properly dampened, a thoroughly saturated portion of the band maybe brought to the topof the roller by merely turning the latter.'

My invention further consists of a reservoir communicating with the cup, as fully described hereafter, so that the latter can be replenished ,with water without removing the roller or band.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation. On reference to" the accompanying drawing, which forms a part of this specificationl l Y Figure 1 is a sectional elevation of my improved damping'deviee; and

Figure 2, a plan view.` l

A is an oblong box or cup, in the upper edge of which are recesses adapted for the reception of the journals of a roller, B, ,and round the latter extends an endless band, a, of felt, cloth, or other suitable material, which hangs from the roller nearly to the bottom of the cup. At one end of the cup -is a reservoir, D, which conm` municates with the interior of the cup. The cup is partially lled with water, and the roller AB is turned so that every portion of the band ais passed through the water and thoroughly saturated, when the device will be ready for use. The ordinary damping device, consisting of a sponge inserted in a shallow cup containing water, is inefticient, as the external portions of the sponge soon become dry, and the Water cannot vbe extracted without exerting considerable pressure. The surface of the sponge, also, is generally so irregular thawJ it is diicult to thoroughly dampen large stamps, bands, or other similar articles. In the above-described device the cloth or band a is of such a' thickness that it'ivill retain a considerable quantity of-ivate1, so that the hand or a stamp may be moistened by merely pressing it slightly against the band. Should the exposed portion of the band become dry,.it is`only necessary to turn the roller, so as to bring to the top of the same a part of the band previously immersed' in the water. Long stamps orl gummed bands may be moistened by pressing them against and drawing them over the cloth, lthe roller B turning and carrying with it the cloth, so that a freshly wet surface is presented to every portion of the stamp. '.lheA cup may be readily replenished with Water by introducing lthe latter into the reservoir D, the necessity of removing the roll'er and band being thus avoided. A lat plate having projections at the ends fitting recesses in the edges of the cup may be substituted for the roller, the plate being reversed whenever the"exposed portion of the band becomes too dry.

I claim as my invention, and desire to secure by Letters Patent- 1. The cup A, baud a, and roller B, or its equivalent, the whole being constructed and operating substantially, as and for the purpose described.

2. The lreservoir D, in combination with the cup A, and the roller and band, or't'heir equivalents, for the purpose set forth.

In testimony whereof I have signed myname to this specification in the presence of two subscribing Witnesses.

PHILIP HILL.
